National Union of Mineworkers

TThe National Union of Mineworkers (NUM) is a trade union for coal miners in the United Kingdom which was formed in 1945. It took part in the national miners' strikes of 1972, 1974, and 1984-5, and it had 170,000 members when Arthur Scargill became leader in 1981. However, the failure of the Miners' strike of 1984-85, the privatization of the coal industry, and the closure of most of Britain's pits led to its membership declining to 100 in 2015.
